MicroBT WhatsMiner M70 (214Th/s)
Air cooling
Description
The MicroBT WhatsMiner M70 (214Th) is a next-generation SHA-256 ASIC miner engineered for high-efficiency Bitcoin mining
in professional environments. Powered by advanced 5nm chip technology, the M70 delivers a strong 214 TH/s hashrate while
maintaining exceptional energy efficiency at just 14.67 J/Th — making it one of the most power-optimized air-cooled
miners in its class.
Designed for serious miners seeking maximum output with controlled operating costs, the WhatsMiner M70 combines
computational strength with refined thermal architecture. Its dual high-performance cooling fans ensure stable heat
dissipation under sustained workloads, allowing consistent performance even during extended mining cycles.
With a total power consumption of approximately 3140W, the M70 strikes an ideal balance between hashrate density and
electrical efficiency. The compact chassis (430 × 155 × 226mm) and manageable 13.5kg weight make it suitable for
scalable rack deployments and structured mining farm layouts.
Built for reliability and operational longevity, the M70 features industrial-grade components and optimized airflow
design to maintain system stability under demanding conditions. Ethernet connectivity ensures secure and straightforward
integration into both small and large-scale mining infrastructures.

Frequently Asked Questions
Customer Reviews
Phenomenal hash rate stability. I've been monitoring it closely and the variance is less than 2%. That's engineering excellence right there.
Definitely worth considering if you're in the market. Good balance of price, performance, and efficiency. No major drawbacks.
Fine for what it is. Not the most efficient but it's reliable. If reliability matters more than efficiency to you, this is a solid choice.
It's an okay miner. Gets the job done but the fan noise is something else. Had to move it to the garage. Still, it's profitable so there's that.
The build quality inspires confidence. Thick PCBs, quality capacitors, and solid soldering. This is hardware built to last years of 24/7 operation.
It's a miner. Nothing to write home about but it does generate crypto. Just wish the fan controller was a bit smarter.
